NPR/PBS leans leftwards
However if you're claiming 'Far from fair' you're discounting how many conservatives they have on air, entirely conservative based shows like Tucker Carlson, The Editorial board of the WSJ, the 60%-80% conservative panel of the McLaughlin group, Religious programming, local politics, et al. And that's before even talking about the number of conservative guests and think-tanks on the 'Liberal' shows.
A) NPR/PBS bends over backwards to make sure conservatives have a voice
B) When's the last time you heard NPR/PBS cut someones a conservatives mic because they were winning the argument?
